MACHINE FOR SECURING HEADS TO RODS.

SPECIFICATION forming part of Letters Patent No. 509,683, dated November28, 1893.

Application filed February 6. 1893. Serial No. 461,190. (No model.)

To aZZ whom it may concern.-

Be it known that I, DANIEL M. REDMOND, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and ImprovedMachine forHeading Rods, of which the following is a full, clear, andexact description.

The object of the invention is to provide a new and improved machine forrapidly and securely fastening heads or tips on the outer ends of rods,used in the manufacture of key rings and other articles.

The invention consists of certain parts and details, and combinations ofthe same, as will be hereinafter described and then pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front view of the improvement. Fig. 2 is a transversesection of the same on the line 2-2 of Fig. 1. Fig. 3 is an enlargedplan view of one of the dies. Fig. 4 is a side elevation of the samewith parts in section on the line 4-4 of Fig. 3. Fig. 5 is an enlargedplan view of one of the tips or heads. Fig. 6 is a sectional sideelevation of the same on the line 6-6 of Fig. 5; and Figs. 7 and 8 areside elevations of the finished r0 s.

The improved machine for heading or tipping rods is provided with asuitably-constructed frame A, formed with the base A, fastened on abench B, or other suitable support.

In the upper end of the frame A is jonrnaled a main driving shaft 0,connected with other suitable machinery for imparting a continuousrotary motion to the said shaft. On the front end of the shaft C isformed a crank pin 0', engaged by the head D of a pitman D,pivotally-connected with a cross head E, mounted to slide vertically insuitable guideways A arranged on the front end of the frame A, asplainly illustrated in Figs. 1 and 2.

In the lower end of the cross head E is secured a die F, opposite whichis arranged a similar die G, each of the said dies F and G being alikein construction, that is, the face of each die is formed with a centralrecess G from which extends rearwardly arranged re cesses G to the outeredges of the die. The radial recesses G2 are of sufficient size toaccommodate the rod to be headed, while the central recess G is adaptedto receive the head or tip, and when the two dies are moved toward eachother, the die compresses the sides of the head or tip to fasten thesame onto the rod.

As shown in Figs. 5 and 6, the sides of each cup'shaped head may beslotted so that the individual sections of the head can be readilycompressed onto the end of the rod to fasten the head in place by thepressure of the dies. The lower die G is formed with a shank G held inthe head H of a rod H, and adapted to be fastened in the said head by aset screw H See Fig. l. The rod His mounted to slide loosely in averticallydisposed sleeve 1, formed near its upper end with exteriorscrew threads engaged by a nut J, mounted to turn in a suitable socketformed in an offset A arranged on the base A of the frame A. The nut Jis normally held in place in the socket A by a set screw K, screwing inone of the said sockets, as plainly shown in Fig. 2.

The head H of the rod H is adapted to be seated on the upper end of thesleeve I so that the latter, when moved up or down, regulates thelowermost position of the die. The lower end of the rod H is formed witha shoulder H adapted to be engaged by a wedge L, secured in the rim of acam L, mounted" to turn on a pin N, secured in the head 1', formed 011the lower end of the sleeve I, the said cam L being provided with asuitable handle L for conveniently turning the said cam L on the pin Nto raise the rod H so as to move the die G toward the die F. When thehandle L is moved into an uppermost position, as shown in Fig. 2, thenthe shoulder H of the rod H drops off one side of the wedge L so thatthe rod H assumes a lowermost position by its own weight thereby movingthe die Gr away from the die F a suitable distance below the lowerwostposition of the said die F. It is understood that when the sleeve I israised or lowered by turning the nut J, as above described, the head Iis likewise raised or lowered with the cam L, so that the die G may bemoved nearer to or farther from the die F when the latter is in alowermost position. Now, in order to fasten the head or tip onto IOC theend of the rod, I place the loose cup shown in Figs. and 6 onto the endof the rod and then place the latter into one of the recesses G so thatthe head rests in the central recess G of the die G. The operator thenpresses the handle L downward so that the cam L forces the rod H toslide upward,

' whereby the die G with the rod and head on its top surface, is movedupward toward the reciprocating die F, which latter on account of itsmovement hammers or presses the sides of the head or vtip onto the rod,so that the head is securely fastened to the rod. The

operator then swings the handle L upward to permit the rod H to drop asufficient distance below the upper die F when the latter is in alowermost positiou,to conveniently remove the finished rod and insertanother without stopping the motion of the upper a frame, a verticallyreciprocating die car-' rier, a second die carrier opposite thefirst,and a pivoted vertically turning cam on the periphery of which rests thelower end of the second die carrier, substantially as set forth.

2. A machine of theiclass described, com-' prising a reciprocating diewith a central recess and branch recesses leading from the centralrecess, a second die mounted to slide toward and from the saidreciprocating die and provided with recesses registering with therecesses of the reciprocating die, a rod' carrying the saidsecond die,and a cam for moving the said rod upward to bring the rod and head heldon the second diein contact with the reciprocating die, substantially asshown and described.

3. A machine of the class described, comprising a reciprocating die witha central recess and branch recesses leading from the central recess, asecond die mounted to slide toward and from the said reciprocating dieand provided with recesses registering with the recesses of thereciprocating die, a rod carrying the said second die, a cam for movingthe said rod upward to bring the rod and head held on the second die incontact with the reciprocating die, a sleeve carrying the said cam andforming a bearing for the said rod, and means, substantially asdescribed, for vertically-adjusting the said sleeve, as set forth. v

4. The combination with the frame of a vertically reciprocating upperdie-holder, a

L sleeve thereunder provided with an externally threaded upperend,.alnut on said end for supportinga-nd adjusting the sleeve, a cammounted on the lower end of the sleeve and .a die carrying rod extendingdown through the sleeve and resting on the cam, substantially as setforth.

5. The combination with the upper reciprocating die holder,of the lowerdie-carrying rod having a shouldered lower end, and a pivoted verticallyturning cam having a shoul- .d-ered peripheryon which said rod rests,sub- :stantiall y asset forth.
